Weekend thunderstorms rolled through the area are expected to give way to a blistering hot and sticky week.

“It’s going to feel the most uncomfortable it’s felt all summer,” Kevin Donofrio, a National Weather Service meteorologist in suburban Chicago, said of the expected heat wave.

Temperatures in Chicago and stretching into Iowa, Missouri and Kansas and up into Wisconsin are expected to reach 90 degrees by Thursday or Friday, with the same story — though perhaps a bit warmer — anticipated in Minnesota. And in all these areas, the humidity is going to make the temperatures feel like they have reached and even passed the 100-degree mark.

“Anybody that’s out and about running around is going to have to limit their exercise because of the heat,” said Tony Zaleski, a weather service meteorologist in Chanhassen, Minnesota, explaining that the expected temperatures in the upper 90s would be a good 10-12 degrees above normal for this time of year.

In Austin, high temperatures are expected to hover in the low 80s on Monday and Tuesday before ticking up to 88 on Wednesday before reaching the low 90s on Thursday and Friday.

The National Weather Service is warning heat index values are expected to reach 100 to 110 on Thursday and Friday afternoons.

Thunderstorms will be possible in the Austin area tonight and Tuesday night, along with periodic chances late in the week.

On Sunday, thunderstorms with winds greater than 40 mph rolled through Chicago, Iowa and other parts of the Midwest, the most violent of which apparently hit eastern Iowa.

There, storms, along with two confirmed tornadoes knocked down trees and damaged homes and businesses. In Walford, firefighters had to rescue a man from the rubble of a house that collapsed. The tornadoes, one in Jackson County and one in Scott County, were on the ground for a short time and no injuries were reported with either.
